Abstract

An experimental research technique is suggested to investigate cross profile generation processes for thermogas dynamic parameters of combustion products in liquid-fuel microthrusters. The technique is based on a modular structure for microthrusters with self-inflammable propellants. The structure consists of regular agitating head and replaceable insertions to investigate flows of the combustion products from agitating head up to nozzle inlet of the microthruster. Experimental results are presented to demonstrate efficiency oj the technique to reveal basic relationships for generation processes in regard to thermogas dynamic parameters of combustion products in liquid-fuel microthrusters.
